单级反激(a19)triac调光led驱动器开发板
this marvell® single-stage flyback (a19) triac-dimmable led driver evaluation kit has been developed for evaluating the performance of the marvell 88em8183, a deep dimming, single-stage ac/dc constant current controller for replacement of offline led lamps and luminaires. the evaluation kit includes an a19 lamp with a marvell 88em8183 driver board developed for a 60w replacement lamp with a 30v/300ma led load, an additional driver board, quick start guide, user manual, design files, transformer specification and test reports. as this design targets the global led market, it can be ordered as either a high-voltage 220vac input version or as a low-voltage 110vac input version.
the evaluation kit’s a19 lamp can be used to quickly verify the driver’s high level of dimmer compatibility. further performance and evaluation tests can be conducted on the led driver board, which can also provide the basis for product development.
the evaluation kit is based on the 88em8183 led driver, a deep dimming single-stage ac/dc constant current controller, designed for offline dimmable led lighting applications. through marvell’s innovative mixed-signal architecture and signal processing technology, 88em8183 delivers down to 1% deep dimming and the highest compatibility with a wide range of wall box (triac) dimmers.
the primary side control topology eliminates the need to use opto-couplers and any other associated secondary feedback circuit, thus improving system reliability. the embedded digital core and analog circuit manages dimmer load requirements and thereby eliminates the need to use external bleeder circuits. in addition, 88em8183 integrates a high voltage start up power supply circuit, hence eliminates the usage of external start up circuits. with its high level of integration, the 88em8183 significantly reduces the external components required for a dimmable led driver to 50% fewer than competitive solutions. this dramatic reduction in component count produces a small form-factor pcb enabling led lighting adoption in cost and space challenged applications such as retrofit lamps.
